Exposure, hazard, and vulnerability all contribute to Schistosoma haematobium re-infection in northern Senegal.

ABSTRACT:

Background

Infectious disease risk is driven by three interrelated components: exposure, hazard, and vulnerability. For schistosomiasis, exposure occurs through contact with water, which is often tied to daily activities. Water contact, however, does not imply risk unless the environmental hazard of snails and parasites is also present in the water. By increasing reliance on hazardous activities and environments, socio-economic vulnerability can hinder reductions in exposure to a hazard. We aimed to quantify the contributions of exposure, hazard, and vulnerability to the presence and intensity of Schistosoma haematobium re-infection.

Methodology/principal findings

In 13 villages along the Senegal River, we collected parasitological data from 821 school-aged children, survey
